Befestigungsvorrichtung für die elektrischen Heizkörper eines GargerätesFixing device for the electric radiators of a cooking appliance

j"' Die Neuerung betrifft die Befestigungsvorrichtung für elektrische Heizkörper, welche in die Muffel eines Gargerätes hineinragen.j "'The innovation relates to the fastening device for electrical radiators, which protrude into the muffle of a cooking appliance.

f Es sind Gargeräte bekannt, welche mit in der Muffel umgewälzter Heißluft betrieben werden. Dabei befindet sich an der Muffelrückwand ein Umluftgebläse, welches die Luft zentral aus der Muffel ansaugt und anschließend durch seitliche Luftleitkanäle j. wieder in die Muffel zurück bläst. In den seitlichen Luftleitkanälen sind elektrische Heizkörper angebracht, um die vorbeistreichende Luft auf die gewünschte Gartemperatur zu erwärmen. Die Heizkörper sind durch die Rückwand des Gerätes geführt und ragen waagrecht in die Luftleitkanäle. Wenn ein elektrischer Heizkörper ausgetauscht werden soll, muß das Gargerät von der Rückseite her zugänglich sein, um die notwendigen Montagearbeiten vornehmen zu können. Hierzu ist es erforderlich, das Gerät von seinem Standort wegzurücken, was einen, erheblichen Arbeitsaufwand erfordert, weil derartige Geräte in Großküchen ein nicht unbedeutendes Gewicht haben und oftmals zwischen anderen Großküchengeräten installiert sind.f There are cooking devices known which are circulated with in the muffle Hot air can be operated. There is a circulating air fan on the back wall of the muffle, which extracts the air centrally from the Sucks in muffle and then through lateral air ducts j. blows back into the muffle. In the side air ducts electric heaters are attached to heat the air passing by to the desired cooking temperature. The radiators are led through the rear wall of the device and protrude horizontally into the air ducts. If an electric If the radiator is to be replaced, the cooking appliance must be accessible from the rear in order to make the necessary To be able to carry out assembly work. To do this, it is necessary to move the device away from its location, which Requires considerable work, because such devices in large kitchens have a not insignificant weight and often installed between other commercial kitchen appliances.

Der Neuerung liegt die Aufgabe zugrunde, das Auswechseln der elektrischen Heizkörper zu erleichtern, intern dies vob der Gerätevorderseite her ohne Demontage der Rückwand ermöglicht wird.The innovation is based on the task of replacing the to facilitate electric radiators, internally this vob the Device front is made possible without dismantling the rear wall.

Zur Lösung dieser Aufgabe werden die im Schutzanspruch angegebenen Merkmale vorgeschlagen.To solve this problem are specified in the protection claim Features suggested.

Es ist bei einer solchen Befestigungsvorrichtung lediglich erforderlich, eine Befestigungsmutter zu lösen, den Heizkörperflansch mit seiner Dichtung abzuziehen und die Heizkörper so weit aus der Rückwand herauszuziehen bis die Anschlußkabel zugänglich sind.It is only with such a fastening device required to loosen a fastening nut, the radiator flange with its seal and pull the radiator out of the rear wall until the connection cable are accessible.

Die Muffelrückwand 3 kann aus relativ dünnem Blech bestehen, denn der Befestigungsflansch 1 erlaubt die Montage mehrerer Heizkörper, ohne daß eine Gefahr der Verformung der Muffelrückwand besteht. Es ist auch nur eine einfache Lochung der Muffelrückwand notwendig, nämlich nur ein Längsschlitz 11
im Bereich der Heizkörperdurchtrittsöffnungen und die beiden Befestigungslöcher 12 für den Befestigungsflansch 1. Die
Erdung kann über einen Ansatz 13 am KeizkörperxläuEuii gewährleistet werden, so daß ein zusätzliches Kabel nicht notwendig ist.
The muffle rear wall 3 can consist of relatively thin sheet metal, because the mounting flange 1 allows the assembly of several radiators without the risk of deformation of the muffle rear wall. Only a simple perforation of the muffle rear wall is necessary, namely only one longitudinal slot 11
in the area of the radiator through openings and the two fastening holes 12 for the fastening flange 1. The
Earthing can be ensured via an attachment 13 on the KeizkörperxläuEuii, so that an additional cable is not necessary.
